On Thursday, the former U.S. Olympic runner admitted to secretly being a Las Vegas escort.

"I realize I have made highly irrational choices and I take full responsibility for them. I am not a victim here and knew what I was doing," the 44-year-old married mother tweeted. "I was drawn to escorting in large part because it provided many coping mechanisms for me when I was going through a very challenging time with my marriage and my life. It provided an escape from a life that I was struggling in. It was a double life."

TheSmokingGun.com reports that the former Olympian (who competed in 1992, 1996 and 2000) used the pseudonym Kelly Lundy and worked with Haley Heston's Private Collection escort service.

"As crazy as I know it seems, I never thought I would be exposed, therefore never hurting anybody," Suzy tweeted. "I do not expect people to understand, but the reasons for doing this made sense to me at the time and were very much related to depression."

She added that she has "been seeking the help of a psychologist for the past few weeks and will continue to do so after I have put things together."

"I cannot emphasize enough how sorry I am to anyone I have hurt as a result of my actions and greatly appreciate the support from family," she wrote. "and those closest to me. I fully intend to make amends and get back to being a good mother, wife, daughter and friend."
